What Is Fomblin® Y 45?
Fomblin® Y 45 is a high-performance perfluoropolyether (PFPE) lubricant engineered for industrial equipment operating under high temperatures, aggressive chemicals, oxygen-rich atmospheres and other demanding environments. With a higher viscosity than Fomblin® Y 15 and Y 25, it provides a thicker lubricating film and enhanced load-carrying capability for medium- to heavily-loaded mechanical components.
